To all whom t may concern.'

Be it known that 1,'JoHN WILLIAM Roonn, a citizen ofthe UnitedStates, residing yat Hornell, in the` county of Steuben and State of New York, have invented certain 'new and useful Improvements in Sewage-Disposal Means and 1 declare the following to be ar full, clear, and exact description-oi' my invention, such as will enable othersskilled in the art to which it appertains toy Arnalre and use the saine, reference being had to the accompanying drawings, and to figures or" reference marked thereon,y which forni" part oflthis speciiication` i i Like gures refer toxlilre parte s My invention relates to `means for dispos- Theobjects oi'my invention are toprovide means for rendering `,sewage harmless without the use of` chemicals and for reclaiming its' fertile. ingredients in a practicalV and eiiicient manner. y, i

Raw sewage, exclusive of trade wastes, lcontains ,salts inv solution, solid matter in suspension `and bacteria.A Toseparateithe solidmatter I providey ayerticalscreen.,l To change? the rsalts ,and destroy ,the bacteria and alter` theobnoriijous` gases, 1j provide a wall built upof electrolytic` and other filter elements, thesaidscreenbeing one Aof the elements and an adjoining floor, madey upk of ironplates, beinganother ofthe elements,

whichy produce `the electrolytic action. The said iron door is positioned outside the said screen andfhas means for heating anddrying theresidue leftfrorn the sewage. vAfter the sewage has filtered through the said wall,fit

vis passed through a tank, ,where the iiltralte is sterilized and allowed to flow, in a harmless condition, to some water course. d I

,Thev means ,whichr constitute a sewage disposaljplant, embodying my invention, are illustrated in the drawings and described in this ,speciioatiorn` the operation of ,saidy forth.y f

means is explained and iwhat I 'claimr is set of my invention for thedisposing of sewage.
